Struct TextAnnotation 

Source 
pub struct TextAnnotation {
    pub text: String,
    pub x: f64,
    pub y: f64,
    pub fontsize: Option<f64>,
    pub color: Option<Color>,
    pub ha: HAlign,
    pub va: VAlign,
    pub rotation: f64,
}
Expand description

A text label placed at a data-space coordinate.

Created by [Axes::text]. Supports builder-style chaining to customise font size, color, alignment, and rotation.

Fields§

§text: String

The text string to render.

§x: f64

X position in data coordinates.

§y: f64

Y position in data coordinates.

§fontsize: Option<f64>

Optional font size override (in points). None uses the theme default.

§color: Option<Color>

Optional text color override. None uses the theme text color.

§ha: HAlign

Horizontal alignment of the text relative to (x, y).

§va: VAlign

Vertical alignment of the text relative to (x, y).

§rotation: f64

Rotation angle in degrees (counter-clockwise).
